AJUUUUUDA :((((
É PRA HHJ, PFFFF RESPONDER CERTO

Answer 1

Resposta:

A) (2.(5)) +(3.(-2))

6+(-4)+15.(-10)= 9

B) -3² -2.3

-9-5= -14

C) (1/2)²- (1/3). (1/4)

(1/4)- (2/25)= 1/6

D) 2.(1/6)²- 4.(-1/6).(2/3) - 3.(2/3)²

(1/18)+ (4/9) - (4/3) = -5/6

E) 3.(-4)² - 5.(-4)+ 12

48+8= 56

F) (-3)³ + 3.(-3).(-4)+5.(-4)²+1

-27+36+80+1= 90

G) 2.(-4)³ +(-4)²-5.(-4)+4

-128+64+16= -48

H) (1/2)³-2.(-1/2).(1/4)+2.(1/4)²

-(1/8)+(1/4)+(1/8)= 1/4

I) (-2)²+3.(-2)-6.(-2).3+(-2).3²

-4-6-36-18= -64

J) 3.((1/2)² - (-2/3)²) - 5.((1/2)+(-2/3))+ 3.((1/2)²+(-2/3)²)

(3/4)+(4/3)-(5/2)+(10/3)+(3/4)+(4/3)= 5
